PRIORITY CLAIM

This application is a Continuation of and claims priority to U.S. Ser. No. 16/922,979 filed 7 Jul. 2020 which in turn claims priority from U.S. Provisional 62/956,054 filed 31 Dec. 2019 and U.S. Provisional 62/871,158 filed 7 Jul. 2019, the entirety of which are both hereby incorporated by reference.

FIELD

The present disclosure relates generally to cameras and image processing, in particular, systems and methods for capturing and sharing selfie content.

BACKGROUND

Every day people take millions of self-portrait or “selfie” photos. Many of these photos are uploaded to social media platforms and shared as posts that provide updates about the selfie subject to a network of followers. Taking a good selfie is hard and a lot of time is wasted in re-taking photos to get the pose, angle, lighting, background, and other characteristics just right. There is therefore a need to develop a camera system that reduces the number of takes and overall amount of time required to produce a good selfie.

Taking a group selfie is also difficult and one or more people posing for a group photo are frequently cut off or left out of the shot. It would be desirable to have a camera system that allows for easy capture of group selfies that included everyone in a group.

Post capture, uploading selfies to social media platforms is frustrating and time consuming. Manually transferring photos from one device to another and, once on the proper device, from one platform to another adds time and complexity to social media posting. Transfers between devices and platforms and also introduce additional editing time and result in data loss (e.g., accidentally deleted phots, resolution loss, etc.). There is therefore a need to develop a camera system that reduces the overall time needed to post selfies and other items of content to social media platforms.

Previous attempts have been made to solve problems with capturing selfie content, but the arm capture method (i.e., pointing a smartphone camera at one's self and extending the camera away from the face/body to increase the field of view) is still the most commonly used technique. Although highly visible, selfie sticks provide only a marginally longer arm, therefore, maintain the limited capture angle and restricted field of view problems associated with arm capture. Remote timer and tripod systems have also been adapted to smartphones to take selfies but they take a long time to setup and do not provide an efficient way to preview photos before capture. Behavioral adaptions including mirror selfies and asking strangers to take photos have also been adopted but these solutions restrict the conditions in which selfies can be captured. No selfie specific camera solutions have been explored.

Exemplary Embodiments of the System

FIGS. 1-2 illustrate exemplary systems for capturing and sharing pieces of content including selfie images and videos. These systems may, for example, reduce the number of re-takes and overall time required to capture and share pieces of content including selfie images and videos. FIG. 1 illustrates an example embodiment of a selfie image system 100 that may capture and share pieces of content including selfie images. The selfie image system 100 may include a selfie camera 102 that captures pieces of content including a subject 110. The selfie camera 102 may be communicatively coupled to a user device 104 using one or more connections 114 (e.g., a Bluetooth, Wifi, or other wireless or wired connection). The selfie camera 102 may stream a preview 108 of the area within the field of the view of the selfie camera 102 to a user device 104. Using the user device 104 as a remote control, a user may capture a piece of content using the selfie camera 102. In various embodiments, the preview 108 may include a live video showing the subject 110 and surrounding area captured by the image sensor of the selfie camera 102. A user may view the preview 108 to assist the capture process by verifying the subject 110 appears as the user would like before deciding to initiate capture. When the subject 110 appears exactly how the user would like in the preview 108, the user may capture a selfie image or other piece of content using the selfie camera 102 by remotely activating the selfie camera 102 using the user device 104. The preview 108 of the captured image is then sent by the selfie camera 102 to a user device 104 and displayed on a user device display. If the user is happy with how the selfie image or other piece of content turned out, the user may share the selfie image or other piece of content to a social media platform 112. If the user desires to capture another piece of content including the subject 110, the first piece of content may be saved on the user device 104 or discarded and the preview 108 changed from displaying a captured piece of content back to displaying a live video of the subject 110 and surrounding area.

The user device 104 may be a processor based device with memory, a display, and wired or wireless connectivity circuits that allow a user device 104 to communicate with the selfie camera 102 and/or the social media platform 112 and interact/exchange data with the selfie camera 102 and/or the social media platform 112 using a communications path 116. For example, the user device 104 may communicate a message to selfie camera 102 to capture a piece of content and receive a data file including the piece of content in response from the selfie camera 102. The image file may be displayed on a user device display as a preview 108. The user device may be a smartphone device, such as an Apple iPhone product or an Android OS based system, a personal computer, a laptop computer, a tablet computer, a terminal device, and the like. The user device 104 may have an application (e.g., a web app or a mobile app) that is executed by the processor of the user device 104 that may display visual information to a user including the preview 108 before and/or after image capture and a user interface for editing and/or sharing selfie content. One example user interface is shown below in FIGS. 5A-5M. The communications path 116 may include one or more wired or wireless networks/systems that allow the user device 104 to communicate with a social media platform 112 using a known data and transfer protocol. The social media platform may be any known social media application including Twitter, Facebook, Snapchat, Instagram, Wechat, Line, and the like.

FIG. 2 illustrates an example embodiment of a selfie video 200 system that may capture and share pieces of content including videos. To capture selfie videos and other pieces of content the selfie camera 102 connects to a user device 104 using one or more connections 114 (e.g., a Bluetooth, Wifi, or other wireless or wired connection). Once connected to the selfie camera 102 a user device 104 may receive a live video preview 108 of a subject 110 from the selfie camera and display the preview 108 on a user device display. The preview 108 may show the subject 110 and the area surrounding the subject 110 as captured by the image sensor in the selfie camera 102. Once the subject 110 appears as desired in the preview 108, videos and other pieces of content captured by the selfie camera 102 may be streamed to a video streaming platform 202. Remote control functionality included in an application (e.g., mobile app or web app) executed by the processor of the user device 104, may cause a selfie camera 102 to record and/or share selfie videos and other pieces of content on a video streaming platform 202. To share a piece of content on a video streaming platform, the selfie camera 102 may connect to a video streaming platform 202 using a communications path 116. User account information, including account name and login information, may be received from a user device 104 as part of the connection process. A user device connected to the selfie camera 102 may simultaneously connect to a video steaming platform 202 using a communications path 116. A direct communications path 116 between a user device 104 and a video streaming platform 202 and/or a selfie camera 102 and a video streaming platform 202 gives users full control over their user device 104 when live streaming video and other pieces of content (i.e., “going live”) to a video streaming platform 202 because, in the selfie video system 200, the selfie camera 102 is the device streaming video and other pieces of content not the user device 104. Therefore, functionality of a user device 104 is not inhibited when a user live streams pieces of content to a video streaming platform 202 using the selfie video 200 system.

A user device 104 may communicate with the selfie camera 102 and/or video streaming platform 202 and interact and/or exchange data with the selfie camera 102 and/or the video streaming platform 202. For example, the user device 104 may communicate one or more messages to a selfie camera 102 to record and/or stream video and other pieces of content to a video streaming platform 202. In response, the selfie camera 102 may send a message (e.g., a push notification) to the user device 104 indicating a live video stream has started. A user device 104 connected to the video streaming platform 202 will then be able to view the live video stream provided by the selfie camera 102 on a user device display. The user device 104 may have an application (e.g., a web app or a mobile app) that is executed by the processor of the user device 104 that may display visual information to a user including a preview 108 before and/or after video recording and a user interface for streaming, editing, and/or sharing selfie content. The communications path 116 may include one or more wired or wireless networks/systems that allow a user device 104 and/or a selfie camera 102 to communicate with a video streaming platform 202 using a known data and transfer protocol. The video streaming platform 202 may include one or more video streaming servers for receiving videos and other pieces of content from a selfie camera 102 and a plurality video streaming clients for distributing videos and other pieces of content from the video streaming server. To facilitate sharing live video content, one or more communications paths 116 and/or video streaming platforms 202 may include a content distribution network for distributing video content from one or more video streaming servers to a plurality of video streaming clients. The video streaming platform 202 may be any known video streaming application including Twitch, TikTok, Houseparty, Youtube, Facebook, Snapchat, Instagram, Wechat, Line, and the like.

FIG. 3 illustrates more details of the systems shown in FIGS. 1-2 and specifically more details of the user device 104 and a server device 320 that may be incorporated into at least one of the social media platform 112 and/or the video streaming platform 202. The components shown in FIG. 3 provide the functionality delivered by the hardware devices shown in FIGS. 1-2 . As used herein, the term “component” may be understood to refer to computer executable software, firmware, hardware, and/or various combinations thereof. It is noted that where a component is a software and/or firmware component, the component is configured to affect the hardware elements of an associated system. It is further noted that the components shown and described herein are intended as examples. The components may be combined, integrated, separated, or duplicated to support various applications. Also, a function described herein as being performed at a particular component may be performed at one or more other components and by one or more other devices instead of or in addition to the function performed at the particular component. Further, the components may be implemented across multiple devices or other components local or remote to one another. Additionally, the components may be moved from one device and added to another device or may be included in both devices.

As shown in FIG. 3 , a user device 104 may be communicatively coupled to a selfie camera and specifically receive pieces of content (e.g., data files including image data, audiovisual data, and the like) and send and receive messages. Pieces of content received from the selfie camera 102 may be stored in an image data store 306 included in a user device 104. The image data store 306 may store data files including pieces of content in various ways including, for example, as a flat file, indexed file, hierarchical database, relational database, unstructured database, graph database, object database, and/or any other storage mechanism. The image data store 306 may be implemented as a portion of the user device 104 hard drive or flash memory (e.g., NAND flash memory in the form of eMMCs, universal flash storage (UFS), SSDs etc.). To capture and process pieces of content, a user device 104 may include a selfie generator 308. In various embodiments, the selfie generator 308 may be implemented as a stand-alone mobile app installed on a user device, a stand-alone web app accessible by a web browser application, and/or as a plug-in or other extension of another mobile app installed on a user device (e.g., a naïve camera app, photo app, photo editing app, and the like) or web app accessible through a web browser. The selfie generator 308 may be communicatively coupled to a selfie camera 102 and a plurality of other apps (316 a, 316 b, 316 c, etc.) that are executed by a processor of a user device 104.

In various embodiments, the selfie generator 308 includes a selfie camera controller 310, preview logic 312, and a streaming engine 314. The selfie camera controller 310 may send and receive messages and other data from the selfie camera to control camera functionality. For example, the selfie camera controller 310 may receive a message from a selfie camera 102 indicating with selfie camera 102 is powered on and located close enough to the user device 104 to establish a connection. In response, the selfie camera controller 310 may send a message containing a connection request to establish a communication path with a selfie camera 102. The selfie camera controller 310 may send messages including commands for adjusting one or more camera settings (e.g., zoom, flash, aperture, aspect ratio, contrast, etc.) of the selfie camera 102. The selfie camera controller 310 may send messages including commands causing the selfie camera 102 to record video, stream video, and/or capture images. The selfie camera 102 executes the commands and then distributes captured pieces of content to an image data store 306. In various embodiments, the selfie camera controller 310 by execute one or more capture routines for controlling capture of selfie images, selfie videos, and other pieces of content by the selfie camera 102. Capture routines may cause the selfie camera 102 and/or user device 104 to provide a visual or auditory countdown signaling when capture is about to take place. For example, a capture routine may include a 3 to 10 second countdown that incorporates displaying a countdown sequence of numbers (one number per second) on a user device display. The countdown may also include an audio component that audibly counts backward from, for example, 10 to 1. The audio component may be in sync with the user device display so that when the number displayed on the user de-vice display is counted in the audio component. At the conclusion of the countdown, the selfie camera controller 310 may initiate capture of one or more pieces of content. One or more delays can be included in a capture routine to provide additional time to between competing the countdown and initiating capture of one or more pieces of content. Capture routines executed by the selfie camera controller 310 may capture a sequence of, for example, 2 to 5 photos with each captured photo displayed in a preview shown on a user device display.

In various embodiments, when executing a command to stream video and/or other pieces of content, the selfie camera 102 may initiate a connection with a sever device 320 (e.g., a streaming platform server) of a video streaming platform. Once connected to a server device 320 the selfie camera 102 may stream selfie videos and other pieces of content to the server device 320 for distribution to a plurality of streaming platform clients. In various embodiments, the selfie camera 102 may also provide video and other pieces of content for streaming to an image data store 306. The streaming engine 314 may retrieve video and other pieces of content for streaming from the image data store 306 and transfer the video and other pieces of content for streaming to a content API 322 using file/data lossless transfer protocols such as HTTP, HTTPS or FTP. Video and other pieces of content for streaming may then be provided to a content distribution module 326 for distribution to a plurality of clients through a livestream API 328 and/or stored a selfie content database 324. In various embodiments a content distribution module 326 and/or a livestream API 328 may include a media codec (e.g., audio and/or video codec) having functionality for encoding video and audio and other pieces of content received from a selfie camera 102 and or user device 104 into a format for streaming (e.g., an audio coding format including MP3, Vorbis, AAC, Opus, and the like and/or a video coding format including H.264, HEVC, VP8 or VP9) using a known streaming protocol (e.g., real time streaming protocol (RTSP), real-time transport protocol (RTP), real-time transport control protocol (RTCP), and the like). The content distribution module 326 and/or livestream API 328 may then assemble encoded video streams in a container bitstream (e.g., MP4, FLV, WebM, ASF, ISMA, and the like) that is provided by the livestream API 328 to a plurality of streaming clients using a known transport protocol (e.g., RTP, RTMP, HLS by Apple, Smooth Streaming by Microsoft, MPEG-DASH by Adobe, and the like) that supports adaptive bitrate streaming over HTTP or other known web data transfer protocol.

The selfie generator 308 may connect to one or more mobile or web apps 316 b, 316 a executed by a processor of the user device. In various embodiments, preview logic 312 may parse one or more GUIs included in a mobile app and or web app to capture the size, resolution and other characteristics of pieces of content displayed on a social media platform and/or video streaming platform. For example, preview logic 312 may parse HTML, CSS, XML, JavaScript, and the like elements rendered as web app GUIs to extract characteristics (e.g., size, resolution, aspect ratio, and the like) of pieces of content displayed in web app implementations of social media platforms and/or video streaming platforms. Preview logic 312 may extract characteristics of pieces of content displayed in mobile app implementations of social media platforms and/or video streaming platforms by parsing Swift, Objective C, and the like elements (for iOS apps) and/or Java, C, C++, and the like elements (for Android apps). To create a realistic preview of how a piece of content will look on a social media platform and/or video streaming platform, preview logic 312 may include instructions for modifying images, videos, and other pieces of content received from the selfie camera to mirror the characteristics of images, videos, and other pieces of content displayed on one or more social media platforms and/or video streaming platforms. For example, preview logic 312 may crop a piece of content to a size and/or aspect ratio that matches the size and/or aspect ratio of pieces of content displayed in a particular GUI (e.g., post GUI, content feed GUI, live stream GUI, and the like) included in a web app and/or mobile app implementation of a social media and/or video streaming platform. Preview logic 312 may also change the resolution of one or more pieces of content received from a selfie camera to match the resolution of pieces of content displayed in a particular GUI included in a web app and/or mobile app implementation of a social media and/or video streaming platform.

Preview logic 312 can include functionality for configuring previews projected on a user device display to match the orientation of the user device display. For example, preview logic 312 may access a motion sensor (e.g., gyroscope, accelerometer, and the like) included in a user device 104 to determine the orientation of a user device display. Preview logic 312 may then crop the live video feed preview and/or captured piece of content received from the selfie camera 102 to fit the aspect ratio of the user device display at its current orientation. Preview logic 312 may dynamically crop the previews and/or captured piece of content from the selfie camera 102 to match the orientation of the user device display to dynamically change the aspect ratio of the previews and/or captured pieces of content, for example, from portrait to landscape when the user device display rotates from a portrait orientation to a landscape orientation. Post capture, preview logic 312 may display pieces of content as full view content with no cropping, portrait content cropped to a portrait aspect ratio, landscape content cropped to a landscape aspect ratio, and shared content cropped to match one or more GUIs for sharing pieces of content included in a social media and/or video streaming platform. In various embodiments, preview logic 312 may incorporate one or more characteristics of pieces of content extracted from a social media and/or video streaming platform into portrait and/or landscape content. For example, preview logic 312 may modify portrait content to simulate cropping that occurs when sharing one or more pieces of content on a content streaming GUI (e.g., Snapchat snaps, Instagram stories, Facebook stories, and the like) included in a social media and/or video streaming platform. Preview logic 312 may modify landscape content to simulate cropping that occurs when sharing one or more wide angle pieces of content (e.g., a group photo/video captured in a landscape orientation) to a social media and/or video streaming platform. Full view content and/or pieces of content modified by preview logic 312 into portrait content and/or landscape content may be saved to the image data store 306 and/or provided to a content API 322 of a server device 320 using as file/data lossless transfer protocols such as HTTP, HTTPS or FTP. Pieces of content received by a content API 322 may be shared to a social media and/or video streaming platform through a posting API 330.

In various embodiments, preview logic 312 may include one or more routines for editing previews and captured pieces of content. Preview logic 312 may edit captured video by segmenting recorded video and other pieces of content into clips (i.e., 1 to 30 second segments). One or more routines for editing video clips and other pieces of content may also be included in preview logic 312. In various embodiments, preview logic 312 may edit video clips and other pieces of content using one or more video editing filters. For example, preview logic 312 can include editing filters that pan within a scene in any direction (e.g., horizontal, vertical, diagonal, and the like); zoom in to and/or zoom out from one more areas of a scene; show movement within a scene in slow motion; and sync one or more audio clips with playback of a video clip. Preview logic 312 may combine one or more editing filters to enable more advanced editing functionality. For example, preview logic 312 may combine a slow motion editing filter with an audio sync editing filter to sync one or more audio clips with playback of a video clip having a slow motion effect to mask the ambient sound distortion that may occur when a slow motion editing filter is applied to a video clip having audio. In various embodiments, preview logic 312 may apply one or more editing filters post capture by first defining a portion of a scene included in a captured video or other piece of content to manipulate with a editing filter. For example, defining a rectangle at the center of the captured video. One or more editing filters may then be applied to manipulate the aspects of a scene within the rectangle (e.g., zoom in on an object within the rectangle, pan from left to right across the objects within the rectangle, and the like). In various embodiments, preview logic 312 may apply one or more stabilization and/or sharpening functions to livestream video, recorded video, recorded video clips, and other pieces of content. For example, a stabilization function may smooth out vibrations and other undesired movement included in recorded scenes and other pieces of content. A sharpening function may reduce blurring of moving objects captured in record scenes and other pieces of content. In various embodiments, preview logic 312 can include one or more background filters that may be applied to change the background of previews or captured pieces of content. To change the background of a piece of content to one or more background filters, preview logic 312 may include instructions for segmenting the background and foreground aspects of a preview and/or captured piece of content. The background elements of one or more captured pieces of content and/or live video previews may then by extracted and replaced with one or more background filters. Background filters may be actual photographs to simulate real like settings and/or virtual scenes simulating virtual reality or mixed reality environments. Pieces of content modified according to one or more editing functionalities of the preview logic 312 may be saved in the image date store 306 and/or provided to a content API 322 of a server device 320 using as file/data lossless transfer protocols such as HTTP, HTTPS or FTP. Pieces of content received by a content API 322 may be shared to a social media and/or video streaming platform using a posting API 330.

The live image sequence preview GUI shows the scene as it will be captured by the selfie camera during execution of a capture sequence. Inputting a capture command to the selfie camera controller that results in performance of a capture sequence will render the exemplary captured image sequence preview GUI shown in FIG. 5G. In various embodiments, the captured image sequence preview GUI may show the first image captured in the capture sequence as a large preview taking up most of the GUI with all the images, in this example 5, captured in the image sequence shown as smaller previews in a bottom portion of the GUI. Selecting one of the smaller previews may display the selected image in the large preview portion of the GUI. More than one photo may be selected in the smaller previews to enable users to take action on more than one photo captured in the capture sequence. Confirming selection of one or more photos will render a captured image sequence action GUI shown in FIG. 5H for each confirmed selected image. In various embodiments, the functionality of the captured image sequence action GUI is the same as the captured image preview GUI in FIG. 5B. When two or more images captured in the image sequence are selected and confirmed taking action on the first photo in the captured image preview GUI may render a captured image preview GUI for the second photo and so on. If only one image captured in the image sequence is selected and confirmed, taking action on the photo may render the live image sequence preview GUI.

FIGS. 5I-M illustrate exemplary content editing preview GUIs for previewing and editing captured selfie content. FIG. 5I illustrates an exemplary content editing live preview GUI displaying live video of a scene provided by a selfie camera. The content editing live preview GUI shows the scene as it will be captured by the selfie camera during execution of a capture command. Inputting a capture and/or video edit command to the selfie camera controller resulting in capture of selfie content will render a define edit area GUI shown in FIG. 5J. In various embodiments, the define edit area preview GUI may include a box defining an area within which one or more effects (e.g., zoom, pan, slow motion, and the like) may be added to edit selfie content. Inputting a capture and/or audio edit command into the selfie camera controller resulting in capture of selfie content will render a record audio edit GUI shown in FIG. 5K. In various embodiments, the record audio edit GUI may record an audio clip that may be synced with selfie content. Recording an audio clip may result in rendering a recorded audio edit preview GUI shown in FIG. 5L. A preview of the recorded audio clip played over the audio of captured selfie content may be displayed in the audio edit preview GUI as well as options for confirming the recorded audio clip for use in content editing and/or recording a new audio clip. Selecting a record new audio clip may transition back to a record audio edit GUI. Confirming use of the record audio clip may transition to an edited captured content preview GUI shown in FIG. 5M. Selfie content including video effects edits added in the define edit area GUI and/or audio edits added in the record audio edit GUI may be previewed in the edited captured content preview GUI. From the edited captured content GUI, selfie content received from the selfie camera and/or edited by the selfie generator may be deleted, saved to a user device image data store, saved to a cloud storage device or other remote data store, set as a wallpaper, shared to a social medial and/or video streaming platform, shared through a messaging platform, and/or coped to a user device clipboard. Any action taken on the edited capture content GUI may result in rendering the content editing live preview GUI on a user device display.

Mounting systems may be removably attached and/or built into the back of the selfie camera to enable quick and secure attachment to a variety of surfaces. Attaching a selfie camera using a mounting system s the perspective of scenes captured by the selfie camera. FIGS. 6-7B pertain to electroadhesion mounting systems and FIGS. 8A-D illustrate exemplary mechanical mounting systems.

FIG. 6 illustrates and electroadhesion device 600 that may be integrated with and or otherwise attached to the selfie camera. In various embodiments, the electroadhesion device 600 can be implemented as a compliant film comprising one or more electrodes 604 and an insulating material 602 between the electrodes 604 and a case and/or device (i.e., the selfie camera). The electroadhesive film may include a chemical adhesive applied to the insulating material 602 and/or electrodes 604 to allow the electroadhesion device 600 to be attached to a case and/or device. Additional attachment mechanisms used to secure the electroadhesion device 600 to a case and/or device can include a mechanical fastener, a heat fastener (e.g., welded, spot welded, or spot-melted location); dry adhesion; Velcro; suction/vacuum adhesion; magnetic or electromagnetic attachment or tape (e.g.: single- or double-sided). Depending on the degree or device portability desired or needed for a given situation and the size of the electroadhesion device, the attachment mechanism may create a permanent, temporary, or even removable form of attachment.

The insulating material 602 may be comprised of several different layers of insulators. For purposes of illustration, the electroadhesion device 600 is shown as having four electrodes in two pairs, although it will be readily appreciated that more or fewer electrodes can be used in a given electroadhesion device 600. Where only a single electrode is used in a given electroadhesion device 600, a complimentary electroadhesion device 600 having at least one electrode of the opposite polarity is preferably used therewith. With respect to size, electroadhesion device 600 is substantially scale invariant. That is, electroadhesion device 600 sizes may range from less than 1 square centimeter to greater than several meters in surface area. Even larger and smaller surface areas are also possible and may be sized to the needs of a given device.

In various embodiments, the electroadhesion device 600 may cover the entire rear surface of a device. One or more electrodes 604 may be connected to a power supply 612 (e.g., battery, AC power supply, DC, power supply and the like) using one or more known electrical connections 606. A power management integrated circuit 610 may manage power supply 612 output, regulate voltage, and control power supply 612 changing functions. To create an electroadhesive force that provides sufficient electroadhesive attraction to support a device, low voltage power from a power supply 612 must be converted into high voltage charges at the one or more electrodes 604 using a voltage converter 608. The high voltages on the one or more electrodes 604 form an electric field that interacts with a foreign object and or other target surface in contact with- and/or proximate to-the electroadhesion device 600. The electric field may locally polarize the target surface and/or induce electric charges on the target surface that are opposite to the charge on the one or more electrodes 604. The opposite charges on the one or more electrodes 604 and the target surface attract to cause electroadhesion between the electrodes 604 and the target surface. The induced charges may be the result of a dielectric polarization or from weakly conductive materials and electrostatic induction of charge. In the event that the target surface comprises a material that is a strong conductor, such as copper for example, the induced charges may completely cancel the electric field. In this case, the internal electric field is zero, but the induced charges nonetheless still form and provide electroadhesive force (i.e., Lorentz forces) to the electroadhesion device 600.

Thus, the adjustable voltage applied to the one or more electrodes 604 provides an overall electroadhesive force between the electroadhesion device 600 and the material of the foreign object and/or other target surface. The electroadhesive force holds the electroadhesion device 600 on the target surface. The overall electroadhesive force may be sufficient to overcome the gravitational pull on the electroadhesion device 600 and a consumer device or other object attached to the electroadhesion device 600. Therefore, the electroadhesive force may be used to hold a consumer device mounted with the electroadhesion device 600 aloft on the target surface. In various embodiments, a plurality of electroadhesion devices may be placed against target surface, such that additional electroadhesive forces against the target surface can be provided. The combination of electroadhesive forces may be sufficient to lift, move, pick and place, mount, or secure a large object on the target surface.

Removal of the adjustable voltages from the one or more electrodes 604 ceases the electroadhesive force between electroadhesion device 600 and the target surface. Thus, when there is no adjustable voltage between the one or more electrodes 104, the electroadhesion device 600 can move more readily relative to the target surface. This condition allows the electroadhesion device 600 to move before and after an adjustable voltage is applied. Well controlled electrical activation and de-activation enables fast adhesion and detachment, such as response times less than about 50 milliseconds, for example, while consuming relatively small amounts of power.

Applying too much voltage to certain materials (e.g., metals and other conductors) can cause sparks, fires, electric shocks, and other hazards. Applying too little voltage generates a weak electroadhesive force that is not strong enough to securely attach the electroadhesion device 600 to the target surface. To ensure the proper adjustable voltage is generated and applied to the electrodes 604 to generate a sufficient electroadhesive force, a digital switch 616 may autonomously control the voltage converter 608. The digital switch 616 may control the voltage output of the voltage converter 608 based on sensor data collected by one or more sensors 614 included in the electroadhesion device 600. The digital switch 616 may be a microcontroller or other integrated circuit including programmable logic for receiving sensor data, determining one or more characteristics based on the sensor data, and controlling the voltage converter based on the one or more characteristics. The digital switch 616 may operate the voltage converter 608 to generate, modify, set, and/or maintain an adjustable output voltage used to attach the electroadhesion device 600 to a target surface.

For example, in response to detecting a conductive target surface (e.g., metal) by the sensor 614, the digital switch 616 may cause the voltage converter 608 to generate an adjustable voltage sufficient to attach and secure the electroadhesion device 600 to the conductive target surface. The adjustable voltage output may also be safe to apply to conductive surfaces and may eliminate sparks, fires, or other hazards that are created when an electroadhesion device 600 that is generating a high voltage contacts and/or is placed close to a conductive target surface. Similarly, when the sensor 614 detects a different surface with different characteristics, the digital switch 616 controls the voltage converter 608 to generate a different adjustable voltage that is sufficient to attach and secure the electroadhesion device 600 to that different surface. For example, in response to detecting an organic target surface (e.g., wood, drywall, fabric, and the like) by the sensor 614, the digital switch 616 may cause the voltage converter 608 to generate an adjustable voltage that may be sufficient to attach and secure the electroadhesion device to the organic target surface without creating hazards. The adjustable voltage may also minimize the voltage output to avoid hazards that may be created when the electroadhesion device 600 is accidently moved. In response to detecting a smooth target surface (e.g., glass) or an insulating target surface (e.g., plastic, stone, sheetrock, ceramics, and the like) by the sensor 614, the digital switch 616 may cause the voltage converter 608 to generate an adjustable voltage sufficient to attach and secure the electroadhesion device 600 to the smooth and/or insulating target surface without creating hazards. Thus, the electroadhesion device 600 has an adjustable voltage level that is adjusted based on a characteristic of the target surface determined by the sensor 614 resulting in an electroadhesion device 600 that can be safely used to attach to various target surfaces without safety hazards.

The strength (i.e., amount of voltage) of the adjustable voltage may vary depending on the material of the target surface. For example, the strength of the adjustable voltage required to attach the electroadhesion device 600 to a conductive target surface (e.g., metal) may be less than the adjustable voltage required to attach the electroadhesion device 600 to an insulating target surface, a smooth target surface, and/or an organic target surface. The strength of the adjustable voltage required to attach the electroadhesion device 600 to an organic target surface may be greater than the adjustable voltage required to attach the electroadhesion device 600 to a conductive target surface and less than the adjustable voltage require to attach the electroadhesion device 600 to an insulating target surface. The strength of the adjustable voltage required to attach the electroadhesion device 600 to an insulating target surface may be higher than the adjustable voltage required to attach the electroadhesion device 600 to an organic target surface or a conductive target surface. The electroadhesion device 600 may be configured to attach to any type of surface (e.g., metallic, organic, rough, smooth, undulating, insulating, conductive, and like). In embodiments, it may be preferable to attach the electroadhesion device 100 to a smooth, flat surface.

Attaching the electroadhesion device 600 to some target surfaces requires a very high voltage. For example, a very high voltage output may be required to attach the electroadhesion device 600 to a rough target surface, a very smooth target surface (e.g., glass), and/or an insulating target surface. An electroadhesion device 600 generating a high voltage output may generate sparks, fires, electric shock, and other safety hazards when placed into contract with- and/or in close proximity to-conductive surfaces. To avoid safety hazards, some embodiments of the electroadhesion device 600 may not generate a high voltage and may only generate an output adjustable voltage sufficient to attach the electroadhesion device 600 to conductive target surfaces, organic target surfaces, and the like.

When the electroadhesion device 600 is moved to a new target surface, the sensor 614 may automatically detect one or more characteristics of the new target surface and/or determine the material type, surface texture, surface morphology, or other characteristic for the new target surface. The digital switch 616 may then modify and/or maintain the adjustable voltage output generated by the voltage converter 608 based on the material type and/or characteristics for the new target surface. To determine the adjustable voltage to generate using the voltage converter 608, the digital switch 616 may include logic for determining the adjustable voltage based on sensor data received from the sensor 614. For example, the digital switch 616 may include logic for using a look up table to determine the proper adjustable voltage based on the sensor data. The logic incorporated into the digital switch 616 may also include one or more algorithms for calculating the proper adjustable voltage based on the sensor data, Additionally, if the sensor 614 detects the electroadhesion device 600 is moved away from a target surface, the digital switch 616 may power down the voltage converter 608 and/or otherwise terminate the adjustable voltage output from the voltage converter 608 until a new target surface is detected by the sensor 614.

The one or more sensors 614 can include a wide variety of sensors 614 for measuring characteristics of the target surface. Each sensor 614 may be operated by a sensor control circuit 618. The sensor control circuit 618 may be included in the sensor 614 or may be a distinct component. The sensor control circuit 618 can be a microcontroller or other integrated circuit having programmable logic for controlling the sensor 614. For example, the sensor control circuit 618 may initiate capture of sensor data, cease capture of sensor data, set the sample rate for the sensor, control transmission of sensor data measured by the sensor 614, and the like. Sensors 614 can include conductivity sensors (e.g., electrode conductivity sensors, induction conductivity, sensors, and the like); Hall effect sensors and other magnetic field sensors; porosity sensors (e.g., time domain reflectometry (TDR) porosity sensors); wave form sensors (e.g., ultrasound sensors, radar sensors, infrared sensors, dot field projection depth sensors, time of flight depth sensors); motion sensors; surface texture sensors; surface profile sensors, surface morphology sensors, and the like. Sensor data measured by the one or more sensors 614 may be used to determine one or more characteristics of the target surface. For example, sensor data may be used to determine the target surface's conductivity and other electrical or magnetic characteristics; the material's porosity, permeability, and surface morphology; the materials hardness, smoothness, surface profile, and other surface characteristics; the distance the target surface is from the sensor; and the like. One or more characteristics determined from sensor data may be used to control the digital switch 616 directly. Sensor data may also be sent to a data analysis module. The data analysis module may refine the sensor data and use it to determine a characteristic and/or material type (e.g., metal, wood, plastic, ceramic, concreate, drywall, glass, stone and the like) for the target surface. The digital switch 616 may then control the voltage output from the voltage converter 608 based on the characteristic and/or material type for the target surface determined by the data analysis module.

The digital switch 616 may function as an essential safety feature of the electroadhesion device 100. The digital switch 616 may reduce the risk of sparks, fires, electric shock, and other safety hazards that may result from applying a high voltage to a conductive target surface. By autonomously controlling the voltage generated by the electroadhesion device 600, the digital switch 616 may also minimize human error that may result when a user manually sets the voltage output of the electroadhesion device 600. For example, human errors may include a user forgetting to change the voltage setting, a child playing with the electroadhesion device and not paying attention to the voltage setting, a user mistaking a conductive surface for an insulating surface, and the like. These errors may be eliminated by using digital switch 616 to automatically adjust the voltage generated by the voltage converter 608 based on sensor data received from the one or more sensors 614 and/or material classifications made by the data analysis module.

As shown in FIG. 7A, to promote safely and improve user experience, the selfie camera 102 and or electroadhesion device 600 may include a mechanism (e.g., button, mechanical switch, UI element, and the like) 716 for actuating the sensor 614 and/or digital switch 616. The sensor 614 and digital switch 616 may also be automatically turned on when the electroadhesion device 600 and/or the selfie camera 102 is powered on. The electroadhesion device 600 and/or selfie camera 102 may also include a signaling mechanism (e.g., status light, UI element, mechanical switch, and the like) for communicating the status of the sensor 614 and/or digital switch 616 to a user of the electroadhesion device 600. The signaling mechanism may be used to communicate that the proper adjustable voltage for a particular target surface has been determined.

In various embodiments, the signaling mechanism may be a status light that is red when the sensor 614 and/or digital switch 616 is powered on and sensing the target surface material or other characteristics but has not determined the proper adjustable voltage for the target surface. The status light may turn green when the digital switch 616 has received the sensor data, determined the appropriate adjustable voltage for the particular target surface, and generated the proper adjustable voltage output and the electroadhesion device 600 is ready to attach to the target surface. The status light may also turn blinking red and/or yellow if there is some problem with determining the adjustable voltage for the particular target surface and/or generating the adjustable voltage output for the particular target surface. For example, the status light may blink red and/or turn yellow when the sensor 614 is unable to collect sensor data, the data analysis module is unable to determine a material type or other characteristic for the target surface material, the digital switch 616 is unable to operate the voltage converter 608, the voltage converter 608 is unable to generate the correct adjustable voltage, and the like.

FIGS. 7A-B illustrate a selfie camera 102 having an electroadhesion device 600 mounting system. In various embodiments, the electroadhesion device 600 may be used to mount the selfie camera to the target surface 714 of any foreign object 712 including walls, mirrors, trees, furniture, and the like. FIG. 7A illustrates a back surface 700 of a selfie camera 102 having an electroadhesion device 600, for example, a compliant electroadhesive film fixed to the back surface 700. FIG. 7B illustrates a side view of a selfie camera 102 mounted to a foreign object 710 using the electroadhesion device 600. The electroadhesion device 600 may include one or more sensors 614 for measuring one or more characteristics of the foreign object 710.

To attach the selfie camera 102 to the foreign object 710, the one or more sensors 614 determine a characteristic of the foreign object 710. Based on the sensor data, the electroadhesion device 600 applies an adjustable voltage to one or more electrodes 604, the adjustable voltage induces a local electric field 720 around the one or more electrodes 604 wherein opposite charges from the inner portion 712 of the foreign object 710 build up around the surface of the electrodes 604. The build-up of opposing charges creates an electroadhesive force between the electroadhesion device 600 attached to the selfie camera 102 and the foreign object 710. The electroadhesive force is sufficient to fix the selfie camera 102 to the target surface 714 of the foreign object 710 while the adjustable voltage is applied. It should be understood that the electroadhesion device 600 does not have to be in direct content with the target surface 714 of the foreign object 710 to produce the electroadhesive force. Instead, the target surface 714 of the foreign object 710 must be proximate to the electroadhesion device 600 to interact with the adjustable voltage on the one or more electrodes 604. The electroadhesion device 600 may, therefore, secure the selfie camera 102 to smooth, even surfaces as well as rough, uneven surfaces. Additionally, the portion of the electroadhesion device 600 including the one or more electrodes 604 may be curved, flat, and or have an adjustable surface to facilitate better contact with the target surface 714.

The mounting plate may also include a pivot for changing the position (i.e., orientation, direction, perspective, and the like) of the selfie camera 102. In various embodiments the position of the selfie camera 102 may be changed when the selfie camera 102 is mounted to a foreign object my moving the selfie camera 102 about the pivot 814. FIG. 8B illustrates a perspective view of an exemplary suction cup 810 mounting system fixed to a selfie camera 102 using a mounting plate 812. FIG. 8C illustrates a flat top view of an exemplary suction cup 810 mounting system fixed to a selfie camera 102 using a mounting plate 812 having a pivot 814 at the base of the suction cup 810. FIG. 8D illustrates a flat front view of an exemplary suction cup 810 mounting system fixed to a selfie camera using a mounting plate 812.

FIG. 9 illustrates and exemplary process 900 for capturing and sharing a selfie image using the selfie camera system shown in FIG. 1 . At step 902, a selfie camera connects to a user device to establish a communication pathway for transferring messages and data. Once a connection is established, a selfie image preview may be provided to a user device, in step 904. The selfie image preview may be a live video stream of a scene as viewed by the selfie camera device. One or more aspects to the selfie image preview may be modified to simulate the appearance so selfie content on a social media and/or video streaming platform. At step 906, a selfie camera receives a capture command from a connected user device and captures a selfie image. The captured selfie image is sent to the connected user device using the connection pathway. At decision point 908, the quality of the selfie image is evaluated by viewing the preview of the selfie image provided by the selfie camera. If the selfie image shown in the preview is acceptable, the selfie image may be saved on a user device and/or shared on a social media platform by connecting to a social media platform using the user device and transferring the selfie image to the social media platform, at step 910. In various embodiments, the selfie generator providing the selfie image preview may automatically connect to a social media platform when a connection is established with the selfie camera device. Once the selfie generator is connected to a social media platform, selfie image previews may be shared on a social media platform directly from a selfie image preview GUI. If a selfie image shown in a selfie image preview is not acceptable, a selfie image may be discarded. To expediting retaking a selfie image, discarding a selfie image may automatically restarts the selfie capture process by generating a live selfie image preview, at step 904. Steps 904 through 908 may be repeated as many times as necessary to generate an acceptable selfie image.

FIG. 10 illustrates an exemplary process 1000 for live streaming selfie content. At step 1002, a selfie camera connects to a user device to establish a communication pathway for transferring messages and data. Once a connection is established, a selfie video preview may be provided to a user device, in step 1004. The video image preview may be a live video stream of a scene as viewed by the selfie camera device. One or more aspects to the selfie video preview may be modified to simulate the appearance of selfie content on a social media and/or video streaming platform. At step 906, a selfie camera receives a live stream command from a connected user device and connects to a social media and/or streaming video platform. The selfie camera may provide streamed video content to a connected user device in step 1008 and simultaneously share streamed video on a video streaming platform at step 1010.
